33 Hz Pure Sine Wave - Ten Hours of deep sub bass frequency for sleep, relaxation, and immersive low frequency listening.

33 Hz sits at the boundary of what the human body feels as much as hears. Below 40 Hz, sound becomes physical — a pressure, a presence in the room.

33 is regarded by many traditions as the most significant number in sacred geometry. The vertebrae of the human spine. The age of enlightenment. Master builders. Whether you believe that or not — at this frequency, something shifts.

Subwoofer or quality headphones recommended for full effect.
